IMPRQVEM ENT lN SWAGING-MACHINES.

Specification forming part of Letters Patent No. 138,617, dated May 6, 1873; applica `on filed February 1, 1873.

To all whom it may concern:

Be it known that I, HENRY M. GRIPIEN, of Bartlett, in the county of Washington and State of Ohio, have invented a new and useful Improvement in Swaging-Machines, of which the following is a specification:

The object of this invention is to furnish a machine for the use of carriage-smiths and metal-workers generally, by means of which the time and labor required for forging the various light irons required in theprosecution of their business may be greatly diminished and the work performed in a superior manner; and it consists in the construction and arrangement of parts hereinafter described.

In the accompanying drawing, Figure lis a front elevation of the machine with a part broken away to show the spiral spring of the upper or hammer dies or swages. Fig. 2 is a side view, partly in section, to show the mode of moving and adjusting thelower die or swage plate. Fig. 3 is a detail, showing the means by which the die-plate is rocked or turned from a horizontal to an inclined position. Fig. 4. is a top view of the die-plate and die-plate bed. Fig. 5 is a view of a removable plate which clamps onto the die-plate for receiving iiat surfaces. Fig. 6 is a view of a portion of the die plate. 4

Similar letters of reference indicate corresponding parts.

A is the bed-plate of the machine, which is elevated on an iron frame, B, which rests upon the iioor. At each end of the bed-plate is an arm, O, which supports a stand, D. E E are vertical rods supported in the jaws F F of this stand, as seen in the drawing. G G are spiral springs on the rods E E. H. is the bar which carries the upper swages or dies I. The rods E E pass through the ends of this bar, and the bar rests upon the top of the spiral springs G G. J J are screws which fasten the bar to the rods. The rods, with the bar thus connected, play freely` up and down in the jaws F F. The down action is produced by means of a treadle, K, connected with the bar by the upright rods L L, horizontal rod M, and inclined rods N N. (See Fig. 1.) Theback or -upward motion is produced by the recoil of the spira prings. O represents the stems or hamme ends of the dies I, which project above the Fig. 1.

The bar H is made in two l` chamber and spring for each die of which spring is upward and con; a shoulder on the stems, which I in the position seen in the dra fng. When one of the dies is struck with a i jammer it is instantly raised after the blow y the recoil of the spring. 1

l? is the die-plate, having on it ace grooves which correspond with the gr ves in the faces of the hammer-dies I. l e die-plate may be constructed to receive o or more removable dies, as seen at Q, and i lay have one or more die-holes, It, for punchi 1g, the hammer-dies being made to correspo d, as seen in the drawing. S is the die-pla` bed.. The die-plate is held to this bed bt the ways or rts with a he pressure ant against eps the dies guides T T on the bed and the g ooves u u at the ends of the plate. The u er sides of these grooves u u are cog-racks as seen in "Fig 2. W is a sector-wheel atl achend of the bed, which engages with th racks V, by means of which the die-plate is bved and adjusted on the bed laterally to s it the operator. One of the sectors W ha an arm, X, and thumb-screw Y, by means if which the die-plate issecured in any des ed position. The sectors W are on the ends f a shaft or rod, Z, which passes through th ,round cylindrical bar Z. This bar is sta onary on the bed-plate A of the machine. bed S is fitted to this bar, as en in Fig. 3, so that it is given, to a limited g lxtent, a rollingmotion, produced by means of the screw a, which passes through the fra e B, as seen in Fig. 2, and the bale b, which` s attached to the bed S by means of the ears 1 l at each end. The screw a works through th arm cl of the bale as through a nut, and wh .j l it is turned the die-plate and bed S are ro ed or turned from a horizontal to an inclin position in either direction. When so turn 1 the die-plate may be moved, as before descl bed, laterally on its bed, so as to correspond wi h the position of the hammer-dies above. Tl clamp-plate 1r, as seen in i he die-plate ment of the other parts of the machine, as

they may be varied in many Ways Without departing from my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A sWaging-machine, consisting of a series of` movable hammerspring dies or swages and die-plate and die-plate bed, the former plate being made adjustable on its bed and the plate and bed being made adjustable on the bed-plate ofthe machine, substantially as shown and described.

2. The hammer-die bar H, guide-rods E, springs G, and treadle K, substantially as described, for the purposes set forth.

3. The removable clamp e, in combination with the die-plate P, as and for the purposes described. V
